How can I install Adobe Reader on Ubuntu 17.10

Question

I found an outdated solution for installing Adobe Reader here on askubuntu.

I followed the steps but after updating my sources using sudo apt-get update I am getting the following error:

Hit:1 http://archive.ubuntu.com/ubuntu artful InRelease

What can I do to fix this and get Adobe Acrobat installed?

The question itself is actually not a duplicate since OP wants to install Adobe Acrobat and the old solution was outdated.

Answer 1

As stated on the german wiki, Adobe Reader is not in partner sources anymore. Instead it is recommended to install Acrobat DC via playonlinux.

sudo apt install playonlinux
playonlinux

click on "install a program" and wait for the list to get refreshed. Search for Acrobat as soon as it is finished:

You will be guided through the installation. It will take some time but after that you can run Acrobat DC via wine.

Edit: Errata

With current Ubuntu 17.10 and wine 1.9.0 Acrobat DC installation seems to be hanging.

There is a solution from Martin Bruvelis, the maintainer of the install recipe on playonlinux using wine 2.2.1 and the newest download link. It is not yet accepted as a working solution but it will probably the next days.

Download the install-script manually under the section "new sourcecode" revision 2017-11-20 11-38 published on 20 November 2017. Save it in your Downloads directory i.e. under acrobat_new.sh. Then install from the menu using "run local script":

Acrobat DC will install successfully:

Answer 2

There is only one reason to install Adobe Reader when evince is available for all currently supported versions of Ubuntu and if I'm not mistaken is included by default in most if not all releases of Ubuntu. If you don't can easily install it from the repositories with sudo apt install evince This unfortunate reason is Adobe's short sighted attempt to jam XFA down our throats. The XFA format has received a lot of criticism over the years and will probably fade away quietly.

The first version of PDF 2.0 or ISO 32000-2 was published in May of 2017 by the International Standards Organization (ISO). The next ISO/TC 171/SC 02/WG 08 "PDF specification" meeting will be held 23 Apr 2018 to 27 Apr 2018. ISO 32000-2 wass the biggest update to the PDF specification since it has become an ISO standard in 2008.

The good news is that XFA forms are excluded in the new standard along with multimedia and other redundant, outdated or otherwise unportable information. I would expect that as the new standard is adopted, the Adobe attempt to render open source pdf tools useless will ultimately fail, and new and updated FOSS programs which comply to the new standard will become freely available in the repositories. I for one think the PDF Association and the ISO Technical Committees deserve a resounding cheer for their work on this important standard.

Another serious blow to XFA format not being an ISO standard is that it is prohibited in all ISO-standardized PDF subsets that are used for archiving engineering and printing (PDF/A, PDF/UA, PDF/E, PDF/VT and PDF/X).
